.2 '0 all whom it may concern Be it known that we, JoHN VVinLnm'r-Cor-LEY and ARTHUR CYRIL THORNTON, subjects of the Kingof Great Britain,residing at Leeds, Yorkshire, En "land, have invented certain new and;use ul Improvements in Maintaining the Contents of Containers,

Gases, Reservoirs, or the like, Carried by Aircraft, at a RequiredTemperature, of. wh ch the following is a specification. This inventionrelates'to providing j11nproved means forheating the contents ofcontainers, cases, reservoirs, or the like when carried on aircraft,such as torpedoes, herei after generallyreferred to as torpedoes.

It has already been considered necessary to provide heating means forsome-containers,

such as torpedoes, which shouldbe calculated to maintain certainportionsof the torpedo body, when carried by aircraft,'between certainspecifiedlimits of temperature; means have accordingly been proposed by whichthis end may be attained, such for example as an electrically heatedjacket applied-to the exterior surface of the container or tor- Now thepresent invention] refers to-the latter mode of applying'heat attherequired part, the object of thesaid invention being to provide means bywhich the application of such lieat'by exhaust gases may be renderedcontrollable and thereby the temperature of the portion of the torpedocase to which heat is so applied-may 'be'm'aintained within assignedlimits, the absence of such control having been a grave disadvantageincidental to this mode of heating.

' Considering the present invention broadly and in its more simplecharacter, the exhaust pipe conveying the exhaust gases or a portion ofthe exhaust; gases from the eng'ine,;- is constructed so that ithas'gener'ally tw'ooutlets, one 'of'these outlets 'whichwe-will termSpecification oflLetters Batent.

the branch outlet, being arranged ashereinafterdescrib'e d, so that itmay because d to dlrect a portlon of the exhaust gases upon that; partof the torpedo body which is required to be heated, while the other andmore dlrect outlet is situated at a distanceffrom the torpedo body. [Toenable this result to be effectively obtained, the above mentionedbranch outlet is provided with a suitably-shaped mouth,

'andis also made capable 'of angular adjustment, by meansof levers andconnections operated from the fuselage of'the aircraft Ifdesireda'valveor'valves of anysuitable V or Well known construction may.also be appliedto govern either or boththe outlets, and suitable meansare provided by which 'such'valve or valves could be operated by theoccupants of the aircraft, so that by opening or closing suchvalves,-the temperature ofthat portion of the torpedo caseacted upon bythe exhaust gases from the before mentioned branch outlet, would berendered capable of still further regulation. In order to enable, theinvention to be readily understood, we "will" describe one 7 m ans byWhich the abov re' lt maybe 'carriedout. 1 v V Referring now to theaccompanying drawings, Figure- '1 illustrates diagrammatically l inelevation the arrangement of the improvedpheating apparatus with-itsoperating levers and connection to an aircraft engine.

gases.

.In the length of such a pipe 8 and above the torpedo body 7, which maybe suspended beneath the fuselage 1 in the usual manner, is fitted asleeve 8 of a requisite length, the interior surface 9 of the sleeve 8being at a distance from the exterior surface 10 of the pipe 3, and theends of the said sleeve 8 fitted with collars 11 or their equivalentmounted upon the pipe 3 so that the sleeve 8 can be revolved about theaxis of the pipe 3. l-Vitlr in the sleeve 8 the pipe is formed withholes.

12 through which the'exhaust gases may pass into the sleeve 8. 7 j

Collars or clips 13 are also provided for the purpose of maintainingtheendwise po 'sition of the sleeve 8 upon the pipe 3, and at the same timeallowing it to be capable of angular adjustment about the axis of thepipe 3. j

The sleeve 8 carries and communicates with an elongated chamber 14:formed or provided with an elongated mouth 15 so that the gases passingfrom the sleeve 8 into the chamber 14 find their exit by the mouth 15aforesaid. 7

Since the sleeve 8 can be angularly adjusted about the pipe 3, means areprovided .by whlch such adjustment can beeifected from within thefuselage 4, .the sleeve 8 being connected by a link 16 to a rockingmember 17 fitted. with any convenient frictional device.

gases from another bank of cylinders can be adjusted as hereinafterdescribed. The

rocking member 17, by a further link 18,

is connected to an operating lever 19. It

. will be readily understood that by means of the operating lever 19 thesleeve Scan be angularly adjusted about the pipe 3 so as to direct theexhaust gases issuing from its elongated mouth 15, more or less directlyuporrthat portion of the torpedo case 7 which is to be heated, or thesleeve 8 can be adjusted so that the gases issuing from the elongatedmouth 15 carried by the sleeve 8 will not impinge upon the torpedo case,and therefore as the current of gases is caused to impinge more or lessdirectly upon the torpedo case, so will the latter be more or lessheated as requlred. I

The exhaust gases from say one bank of cylinders may be so controlledand utilized.

while the exhaust. gases from an opposite bank of cylinders may passbyanother similar pipe correspondingly fitted with a sleeve carrying anelongated mouth, the exhaust gases from which may act upon another. partof the torpedo case, and the sleeves on both 1 of such exhaust pipes canbe simultaneously controlled by connecting both sleeves, by

By duplicating the lever 16 a second sleeve 8 controlling the exhaustrods or links, to a rocking member, and then by means of the operatinglever 19 both the sleeves can be correspondingly adjusted in position.The drawings show a convenient construction, but obviously in some casesthe whole of the exhaustgases may pass-away by the elongated mouth 15and the more direct outlet 6 be dispensed with.

In concluding this descriptionit should be remarked thatthe'construction of the invention in which a revoluble sleeve isemployed as above described, enables, ifde sired, a heatingjacket to beapplied ex- 7 being quickly and easily varied .orentirely removed.

'cases, reservoirs, orthe like, carried by, aircraft, by exhaust. gasesdelivered from the engine; an engine exhaust pipe having. a sleeve tubeadjustable about the axis. of said exhaust pipe, said exhaust pipehaving apertures through its wallv within said. sleeve, said sleevehaving an open radially extending mouth through which exhaust gases maypass from said exhaust pipe, and meansjfor adjusting said-sleeve aboutthe axis of said exhaust pipeto direct said e xhaust gases onto or.awayfrom the-part to be heated.

2. In. heating devices having the features as claimed by claim 1;constructing the sleeve tube of larger internal diameter than theexternal diameter of the exhaust tube, closing the ends of said sleevetube and mounting same 011 said exhaust tube so as to be capable ofangular adjustment about the axis of said exhaust'tube, so that saidexhaust gases are permitted to pass through the extending mouth of thesleeve tube in whatever angular positionit may be placed. 7,
